I have a model imported from AUTODESK INVENTOR with 3 different fluid bodies frozen, then took ICEM Mesh, we generated a grid to each of them and open it in CFX_PRE, who tells me that the domains are not defined.
One of the domains I have to give conditions of rotation.

My question is:

Is it OK to generate the mesh in ICEM and then define the domains in CFX_PRE?

How would I have to generate the mesh to define a rotating domain in CFX_PRE?
